discouraging purchase
It is overpriced. Some of the pictures will help in construction of models but there are better books available.

Last chance to get quality thinking paper
This is new old stock. The current owner of National does not produce the same product anymore. What they are selling now is the same basic color and quality but does not divide the top row into five sections like this older product does. I bought this because it is what I have used since 1967 for working out math and engineering problems.
